View Agent Direct-Connection Plug-In

Administration

View Agent Direct-Connection Plug-In Administration provides information about installing and configuring

View Agent Direct-Connection Plugin. This plug-in is an installable extension to View Agent that allows

Horizon Client to directly connect to a virtual machine-based desktop, a Remote Desktop Services (RDS)

desktop, or an application without using View Connection Server. All the desktop and application features

work in the same way as when the user connects through View Connection Server.

Intended Audience

This information is intended for an administrator who wants to install, upgrade or configure View Agent

Direct-Connection Plug-In in a virtual machine-based desktop or an RDS host. This guide is written for

experienced Windows system administrators who are familiar with virtual machine technology and

datacenter operations.

Installing View Agent Direct-

Connection Plug-In 1

View Agent Direct-Connection (VADC) Plug-In enables Horizon Clients to directly connect to virtual

machine-based desktops, RDS desktops, or applications. VADC Plug-In is an extension to View Agent and

is installed on virtual machine-based desktops or RDS hosts.

This chapter includes the following topics:

n“View Agent Direct-Connection Plug-In System Requirements,” on page 7

n“Install View Agent Direct-Connection Plug-In,” on page 7

n“Install View Agent Direct-Connection Plug-In Silently,” on page 8

View Agent Direct-Connection Plug-In System Requirements

View Agent Direct-Connection (VADC) Plug-In is installed on machines where View Agent is already

installed. For a list of operating systems that View Agent supports, see "Supported Operating Systems for

View Agent" in the View Installation document.

VADC Plug-In has the following additional requirements:

nThe virtual or physical machine that has VADC Plug-In installed must have a minimum of 128 MB of

video RAM for PCoIP to function properly.

nYou must install VMware Tools before you install View Agent.

NOTE A virtual machine-based desktop that supports VADC can be joined to a Microsoft Active Directory

domain, or it can be a member of a workgroup.

Install View Agent Direct-Connection Plug-In

View Agent Direct-Connection (VADC) Plug-In is packaged in a Windows Installer file that you can

download from the VMware Web site and install.

Prerequisites

nVerify that View Agent is installed.

Procedure

1 Download the VADC Plug-In installer file from the VMware product page at

http://www.vmware.com/products/.

The installer filename is VMware-viewagent-direct-connection-x86_64-y.y.y-xxxxxx.exe for 64-bit

Windows or VMware-viewagent-direct-connection--y.y.y-xxxxxx.exe for 32-bit Windows, where y.y.y

is the version number and xxxxxx is the build number.

The External Port numbers and External IP Address values are used for Network Address Translation

(NAT) and port mapping support. For more information see, “Using Network Address Translation and Port

Mapping,” on page 13.

You can set policies that override these registry settings by using the Local Policy Editor or by using Group

Policy Objects (GPOs) in Active directory. Policy settings have precedence over normal registry settings. A

GPO template file is supplied to configure policies. When ViewView Agent and the plug-in are installed in

the default location, the template file has the following location:

C:\Program Files\VMware\VMware View\Agent\extras\view_agent_direct_connection.adm

You can import this template file into Active Directory or the Local Group Policy Editor to simplify the

management of these configuration settings. See the Microsoft Policy Editor and GPO handling

documentation for details of managing policy settings in this way. Policy settings for the plug-in are stored

in the registry key:

HKEY_LOCAL_MACHINE Software\Policies\VMware, Inc.\VMware VDM\Agent\Configuration\XMLAPI

Disabling Weak Ciphers in SSL/TLS

To achieve greater security, you can ensure that communications that use the SSL/TLS protocol between

Horizon Clients and virtual machine-based desktops or RDS hosts do not allow weak cyphers.

The configuration for disabling weak ciphers is stored in the Windows registry. Changes to these settings

must be done on all machines that run View Agent Direct-Connection Plug-In.

NOTE These settings affect all use of SSL/TLS on the operating system.

Both SSL 3.0 and TLS 1.0 (RFC2246) with INTERNET-DRAFT 56-bit Export Cipher Suites For TLS

draft-ietf-tls-56-bit-ciphersuites-00.txt provide options to use different cipher suits. Each cipher suite

determines the key exchange, authentication, encryption, and MAC algorithms used within a SSL/TLS

session.

You need to have experience editing Windows registry keys using the Regedt32.exe registry editor.

Procedure

1Start Registry Editor Regedt32.exe, and locate this registry

key:HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\SecurityProviders\SCHANNEL

2 Make modifications to the registry.

Windows Version Registry Changes

XP SP3 nIn subkey \Ciphers\DES 56/56 add a DWORD value Enabled with

a value of 0x0.

nIn subkey\Hashes\MD5 add a DWORD value Enabled with a value of

0x0.

Vista and Later nIn subkey \Hashes create a subkey MD5.

nIn subkey \Hashes\MD5 add a DWORD value Enabled with a value

of 0x0.

nFor Windows XP SP3, the registry changes ensure that only the following ciphers are available:

nSSLv3 168 bits DES-CBC3-SHA

nSSLv3 128 bits RC4-SHA

nTLSv1 168 bits DES-CBC3-SHA

nTLSv1 128 bits RC4-SHA

nFor Windows Vista and later, the registry changes ensure that only the following ciphers are available:

nSSLv3 168 bits DES-CBC3-SHA

nSSLv3 128 bits RC4-SHA

nTLSv1 256 bits AES256-SHA

nTLSv1 128 bits AES128-SHA

nTLSv1 168 bits DES-CBC3-SHA

nTLSv1 128 bits RC4-SHA

NOTE When connecting to a Windows XP virtual desktop from Horizon Client, you may need to configure

the cipher list that is supported by the client to include a cipher from the supported list on Windows XP. For

example you may need to configure the client to additionally support TLSv1 128 bits RC4-SHA. By default,

Horizon Client no longer supports this cipher.

If the client is not configured to support any cipher that is supported by the virtual desktop operating

system, the TLS/SSL negotiation will fail and the client will be unable to connect.

For information on configuring supported cipher suites in Horizon Clients, refer to Horizon Client

documentation at https://www.vmware.com/support/viewclients/doc/viewclients_pubs.html.

Replacing the Default Self-Signed SSL Server Certificate

A self-signed SSL server certificate cannot give Horizon Client sufficient protection against threats of

tampering and eavesdropping. To protect your desktops from these threats, you must replace the generated

self-signed certificate.

When View Agent Direct-Connection Plug-In starts for the first time after installation, it automatically

generates a self-signed SSL server certificate and places it in the Windows Certificate Store. The SSL server

certificate is presented to Horizon Client during the SSL protocol negotiation to provide information to the

client about this desktop. This default self-signed SSL server certificate cannot give guarantees about this

desktop, unless it is replaced by a certificate signed by a Certificate Authority (CA) that is trusted by the

client and is fully validated by the Horizon Client certificate checks.

The procedure for storing this certificate in the Windows Certificate Store and the procedure for replacing it

with a proper CA signed certificate, are the same as those used for View Connection Server (version 5.1 or

later). See "Configuring SSL Certificates for View Servers," in the View Installation document for details on

this certificate replacement procedure.

Certificates with Subject Alternative Name (SAN) and wildcard certificates are supported.

NOTE To distribute the CA signed SSL Server Certificates to a large number of desktops using the View

Agent Direct-Connection Plug-In, use Active Directory Enrollment to distribute the certificates to each

virtual machine. For more information see: http://technet.microsoft.com/en-us/library/cc732625.aspx.

Authorizing Horizon Client to Access Desktops and Applications

The authorization mechanism that allows a user to access desktops and applications directly is controlled

within a local operating system group called View Agent Direct-Connection Users.

If a user is a member of this group, that user is authorized to connect to the virtual machine-based desktop,

an RDS desktop, or applications. When the plug-in is first installed, this local group is created and contains

the Authenticated Users group. Anyone who is successfully authenticated by the plug-in is authorized to

access the desktop or applications.

To restrict access to this desktop or RDS host, you can modify the membership of this group to specify a list

of users and user groups. These users can be local or domain users and user groups. If the user is not in this

group, the user gets a message after authentication saying that the user is not entitled to access this virtual

machine-based desktop or an RDS desktop and applications that are hosted on this RDS host.

Using Network Address Translation and Port Mapping

Network Address Translation (NAT) and port mapping configuration are required if Horizon Clients

connect to virtual machine-based desktops on different networks.

In the examples included here, you must configure external addressing information on the desktop so that

Horizon Client can use this information to connect to the desktop by using NAT or a port mapping device.

This URL is the same as the External URL and PCoIP External URL settings on View Connection Server and

security server.

When Horizon Client is on a different network and a NAT device is between Horizon Client and the

desktop running the plug-in, a NAT or port mapping configuration is required. For example, If there is a

firewall between the Horizon Client and the desktop the firewall is acting as a NAT or port mapping device.

An example deployment of a desktop whose IP address is 192.168.1.1 illustrates the configuration of NAT

and port mapping. A Horizon Client system with an IP address of 192.168.1.9 on the same network

establishes a PCoIP connection by using TCP and UDP. This connection is direct without any NAT or port

mapping configuration.

If you add a NAT device between the client and desktop so that they are operating in a different address

space and do not make any configuration changes to the plug-in, the PCoIP packets will not be routed

correctly and will fail. In this example, the client is using a different address space and has an IP address of

10.1.1.9. This setup fails because the client will use the address of the desktop to send the TCP and UDP

PCoIP packets. The destination address of 192.168.1.1 will not work from the client network and might

cause the client to display a blank screen.

To resolve this problem, you must configure the plug-in to use an external IP address. If externalIPAddress

is configured as 10.1.1.1 for this desktop, the plug-in gives the client an IP address of 10.1.1.1 when making

desktop protocol connections to the desktop. For PCoIP, the PCoIP Secure Gateway service must be started

on the desktop for this setup.

For port mapping, when the desktop uses the standard PCoIP port 4172, but the client must use a different

destination port, mapped to port 4172 at the port mapping device, you must configure the plug-in for this

setup. If the port mapping device maps port 14172 to 4172, the client must use a destination port of 14172 for

PCoIP. You must configure this setup for PCoIP. Set externalPCoIPPortin the plug-in to 14172.

In a configuration which uses NAT and port mapping, the externalIPAdress is set to 10.1.1.1, which is

network translated to 192.168.1.1, and externalPColPPort is set to 14172, which is port mapped to 4172.

As with the external PCoIP TCP/UDP port configuration for PCoIP, if the RDP port (3389) or the Framework

Channel port (32111) is port mapped, you must configure externalRDPPort and

externalFrameworkChannelPort to specify the TCP port numbers that the client will use to make these

connections through a port mapping device.

Advanced Addressing Scheme

When you configure virtual machine-based desktops to be accessible through a NAT and port mapping

device on the same external IP address, you must give each desktop a unique set of port numbers. The

clients can then use the same destination IP address, but use a unique TCP port number for the HTTPS

connection to direct the connection to a specific virtual desktop.

For example, HTTPS port 1000 directs to one desktop and HTTPS port 1005 directs to another, with both

using the same destination IP address. In this case, configuring unique external port numbers for every

desktop for the desktop protocol connections would be too complex. For this reason, the plugin settings

externalPCoIPPort,externalRDPPort, and externalFrameworkChannelPort can take an optional relational

expression instead of a static value to define a port number relative to the base HTTPS port number used by

the client.

If the port mapping device uses port number 1000 for HTTPS, mapped to TCP 443; port number 1001 for

RDP, mapped to TCP 3389; port number 1002 for PCoIP, mapped to TCP and UDP 4172; and port number

1003 for the framework channel, mapped to TCP 32111, to simplify configuration, the external port numbers

can be configured to be externalRDPPort=+1, externalPCoIPPort=+2 and externalFrameworkChannelPort=+3.

When the HTTPS connection comes in from a client that used an HTTPS destination port number of 1000,

the external port numbers would automatically be calculated relative to this port number of 1000 and would

use 1001, 1002 and 1003 respectively.

To deploy another virtual desktop, if the port mapping device used port number 1005 for HTTPS, mapped

to TCP 443; port number 1006 for RDP, mapped to TCP 3389; port number 1007 for PCoIP, mapped to TCP

and UDP 4172; and port number 1008 for the framework channel, mapped to TCP 32111, with exactly the

same external port configuration on the desktop (+1, +2, +3, and so on) when the HTTPS connection comes

in from a client that used an HTTPS destination port number of 1005, the external port numbers would

automatically be calculated relative to this port number of 1005 and use 1006, 1007, and 1008 respectively.

This scheme allows all desktops to be identically configured and yet all share the same external IP address.

Allocating port numbers in increments of five (1000, 1005, 1010 …) for the base HTTPS port number would

therefore allow over 12,000 virtual desktops to be accessed on the same IP address. The base port number is

used to determine the virtual desktop to route the connection to, based on the port mapping device

configuration. For an externalIPAddress=10.20.30.40, externalRDPPort=+1, externalPCoIPPort=+2 and

externalFrameworkChannelPort=+3 configured on all virtual desktops, the mapping to virtual desktops

would be as described in the NAT and port mapping table.

192.168.0.3:4172

10.20.30.40:1018 ->

192.168.0.3:32111

In this example, Horizon Client connects to IP address 10.20.30.40 and an HTTPS destination port number of

(1000 + n * 5) where n is the desktop number. To connect to desktop 3, the client would connect to

10.20.30.40:1015. This addressing scheme significantly simplifies the configuration setup for each desktop.

All desktops are configured with identical external address and port configurations. The NAT and port

mapping configuration is done within the NAT and port mapping device with this consistent pattern, and

all desktops can be accessed on a single public IP address. The client would typically use a single public

http://www.vmware.com/products/.

The filename is VMware-Horizon-View-HTML-Access-y.y.y-xxxxxx.zip, where y.y.y is the version

number and xxxxxx is the build number.

Set Up Trusted CA-Signed SSL Server Certificate

You can set up trusted CA-Signed SSL server certificate to ensure that traffic between clients and desktops is

not fraudulent.

Prerequisites

nReplace the default self-signed SSL server certificate with a trusted CA-signed SSL server certificate. See

“Replacing the Default Self-Signed SSL Server Certificate,” on page 13. This creates a certificate that has

the Friendly Name value vdm.

nIf the client's static content is served by the desktop, set up static content delivery. See “Set Up Static

Content Delivery,” on page 18.

nFamiliarize yourself with the Windows Certificate Store. See "Configure View Connection Server,

Security Server, or View Composer to Use a New SSL Certificate" in the View Installation document.

Procedure

1 In the Windows Certificate Store, navigate to Personal > Certificates.

2 Double-click the certificate with Friendly Name vdm.

3 Click on the Details tab.

4 Copy the Thumbprint value.

5 Start the Windows Registry Editor.

6 Navigate to the registry key HKEY_LOCAL_MACHINE\SOFTWARE\VMware, Inc.\VMware Blast\Config.

7 Add a new String (REG_SZ) value, SslHash, to this registry key.
